please help on solving x^2+5x+3=0

and

During the first part of a canoe trip, Ken covered 60km at a certain speed. He then traveled 24km at a speed that was 4 km/h slower. If the total time for the trip was 8 hr, what was the speed on each part of the trip?

ok thanks ill fix it this is only the second time i use this help website because i'm pretty good at math but this subject is confusing for me.

$$(x + \frac{5+\sqrt{13}}{2}) (x + \frac{5-\sqrt{13}}{2}) $$

anonymous · Answer

where did you get the 13 from?

turingtest · Answer

x^2+5x+3=0
does not factor, so you must use the quadratic formula:$$x={-b \pm \sqrt{b^2-4ac}\over2a}$$for equations of the form ax^+bx+c=0
here
x^2+5x+3=0
a=1
b=5
c=3
plug in and solve!
